There is an Iowa non resident tag on E-Bay for sale. Half of the selling price goes to the Iowa DNR. The other half goes to assist in an archery program in schools. You'll have to look it up to find out the whole story.
So if you want to hunt Iowa and help a good cause here's a chance.

I believe they take care of that after the auction ends. If you go to the E-bay add it will Explain better. I just posted it on here incase anyone might be interested. I think it's up to about $2700 with 3 days left. Not exactly cheep. But part does go to a good cause.
I think the add on ebay is the same as the subject line on here if you do a search it should get you close atleast.
